Nonvolatile semiconductor memory device and memory system
Kabushiki Kaisha Toshiba
May 04, 2017 - N°20170125092

A memory device includes a nonvolatile semiconductor memory cell array, a plurality of terminals through which control signals are received to control the memory device, an on-die termination circuit connected to at least one of the terminals and having a variable resistor, and a control circuit. The control circuit is configured to enable the on-die termination circuit in response to ...
Non-volatile memory using bi-directional resistive elements
Freescale Semiconductor, Inc.
September 22, 2016 - N°20160276029

A memory cell includes a first bidirectional resistive memory element (brme), and a second brme, a first storage node, and a second storage node. A resistive memory write to the cell includes placing the first brme and the second brme in complementary resistive states indicative of the value being written. During a subsequent restoration operation, the value as written in ...
Low-flicker variable refresh rate display
Apple Inc.
July 07, 2016 - N°20160196802

An electronic device may have a variable refresh rate display. Static content may be displayed on the display at a lower refresh rate than moving content to conserve power. The display may include an array of pixels. Display driver circuitry in the display may load image data into rows of the pixels. The display driver circuitry may have digital-to-analog converter ...

Method and circuit for detecting usb 3.0 lfps signal
Advanced Micro Devices, Inc.
March 05, 2015 - N°20150067209

A system and method for efficient detection of low frequency periodic signaling (lfps) input signals. A receiver receives two input differential signals that are lfps input signals. The receiver increases the common-mode voltage for each of the two input differential signals and determines two polarity opposite differences between the level shifted intermediate differential signals. The differences are used to generate ...
Apparatus and a method for erasing data stored in a memory device
Arm Limited
December 18, 2014 - N°20140369139

The present invention provides an apparatus and method for erasing data in a memory device comprising an array of memory cells, and configured to operate from a clock signal. The apparatus includes erase circuitry, responsive to receipt of an erase signal in an asserted state, to perform a forced write operation independently of the clock signal in respect of each ...

Method and apparatus for adaptive timing write control in a memory
Arm Limited
August 07, 2014 - N°20140219002

A bit line, which is coupled to a resistive element of a memory cell is set to a first voltage level. The memory cell may be an mram cell or an rram cell. The resistive element is configured to have a first resistance in a first state of the memory cell and a second resistance in a second state of ...
Methods and apparatus for improving backlight driver efficiency
Arm Limited
June 12, 2014 - N°20140159614

An electronic device may be provided with display circuitry that includes a display timing controller, a backlight driver, a light source, and other associated backlight structures. The backlight control circuitry may generate a control signal having an adjustable duty cycle to the backlight driver. The backlight driver may include a boost converter, a current driver, and backlight control circuitry. The ...
Apparatus and method for hidden-refresh modification
Arm Limited
February 13, 2014 - N°20140043919

A system and method for modifying a hidden-refresh rate for dynamic memory cells includes monitoring a control signal from a processor and performing a hidden-refresh of dynamic data at a first refresh rate when the control signal is asserted. The dynamic data is refreshed at a second refresh rate when the control signal is deasserted for a predetermined duration. A ...
